Quick Talk transmits your voice message when the switch change occurs and at intervals you select. Because you provide and connect the switches to your Quick Talk units, they can report changes due to intrusion, tamper, equipment malfunction, liquid level, machinery, pressure, temperature, power, smoke or leakage. The Quick Talk is easily programmed to transmit on your existing or new radio frequency and also encodes the most popular sub-audible coded squelch formats such as Quiet Call® or Digital Quiet Call TM . This enables all of your personnel with JOBCOM, PATRIOT or equivalent two-way radios to hear the voice messages instantly, and to be alerted to the current condition of each monitored location or device. Quick Talk is housed in a weather-resistant enclosure so that it can be installed in a wide variety of indoor and outdoor locations. You don't have to supply AC line power to the Quick Talk because its six internal AA Alkaline batteries will power the unit for about a year. QUICK TALK MODELS AND FREQUENCIES There are two separate Quick Talk models, one for each of the most popular professional radio communications bands. The model number appears on a label on the front of the case and a second label is placed inside the case. MODELBANDFREQUENCY RANGE RQT-150VHF-FM150 to 165 MHz RQT-450UHF-FM450 to 470 MHz Ritron manufactures mobile, portable and base station two- way radios and repeaters for use with Quick Talk, and pioneered the use of Color Dots on radios to identify frequencies. The factory-programmed, default frequencies for Quick Talk are Blue Dot (154.570 MHz) for VHF units, and Blue Star (467.925 MHz) for UHF units. The instruc- tions on page 4 describe how easy it is for the owner to change the Quick Talk transmit fr…

FCC ID: AIERIT10-450 Page 4 of 10 RQT Theory of Operation Introduction Ritron RQT Quick Talk units are comprised of two (2) printed circuit board sub-assemblies. These are the Control and Transmitter Boards. The Control Board is common to both the RQT-150 and RQT-450 models. Below is a block diagram of the Control Board. A detailed description of the circuit blocks follows.

DET F.C.C. Equipment Authorization Application Exhibit. RITRON, INC. FCC ID: AIERIT10-450 Page 5 of 10 1. DC Voltage Distribution Operating power for the radio is derived from two sources: 1.1.A. Internal Battery Pack The internal battery pack (B101) consists of six AA size alkaline or NiCd rechargeable batteries. These supply approximately 6-9 Volts to the RF interference filter (L101, L102, C109, C110) located on the control board. This power is routed through a Schottky diode to a power supply summing node at the fuse (F101). 1.1.B. External Power Supply Connections An external power supply in the range of 9-15 VDC can be connected to the screw terminals marked DC+ and DC-. These two terminals run through a RF filter (L103-L106, C101-C103) this filtered supply is then fed through a diode to a regulator transistor (Q107) and power fail circuitry (Q101). Q107 is configured as a series-pass emitter follower regulator. Zener diode CR106 and R109 supply a bias voltage (10 VDC) to the base of Q107. The emitter is filtered by C104 and fed through PJ103 and R102 to charge the battery pack when rechargeable batteries are used. PJ103 should be removed when using an external primary power source and the alkaline batteries as a backup power source. The output of Q107 is also fed to the power supply summing point at fuse (F101). This series pass regulator is needed to protect the voltage regulator IC101 from voltages above 10 VDC. The voltage at F101 (+VB) is filtered by C106 and C107 to reduce noise. The…

FCC ID: AIERIT10-450 Exhibit Type: Parts List & Tune-Up Information Page 1 of 5 EXHIBIT TYPE:Tune Up Procedure DATE:November 10, 1998 Equipment Required:F.C.C. Part 68 Registered Telephone Set w/Rotary/Pulse Dialing and modular cable. Radio Frequency Communications Test Set with the following capabilities: - RF Power Meter- RF Frequency Error Meter - FM Modulation Meter- Oscilloscope Type Modulation Display Oscilloscope or high impedance Voltmeter (Do not use a low-cost “VOM”.). Procedure: Install six (6) fresh AA Alkaline batteries in the RQT-Control Board. Place jumper PJ102 in the shorted position. Set R219 the Voice Deviation Adjustment fully counter-clockwise. Connect the telephone set to the RQT’s modular jack. Connect the RQT antenna connector to the input of the RF Communications Test Set. Use this instrument per its manufacturer’s instructions to make the measurements below. Dial 978 on the telephone to restore factory default programming information. Dial 12yyyyyy to set the desired transmit frequency where yyyyyy is the transmit frequency (i.e. dialing 12154570 will set the transmit frequency to 154.570 MHz). The test frequency used for RQT-150 VHF units is 153.100 and for RQT-450 units it is 460.100 MHz. Use these frequencies to align the unit to assure proper operation across the standard frequency range. Dial 411 to activate the RQT transmitter. Measure the voltage with respect to ground on C323 and adjust the shielded variable inductor L303 on the RQT transmitter for a reading of x.xx Volts for VHF units and y.yy for UHF units. Activate the transmitter and measure the transmitter power output. This should be between 100 and 120 milli-Watts. There are no adjustments provided to change this power output. Activate the transmitter and adjust C310 on the RQT transmitter module through zero frequency error and then as close as possible to zero frequency error with respect to the programmed transmit frequency. Dial 22071 and then 411 on the telephone. The RQT transmitter will activate with a 071 code Digital Quiet Call (DQC) sub-audible coded squelch signal applied as modulation. Repeatly adjust R212 on the RQT Control Board for +/- 1000 Hz deviation and R310 on the RQT transmitter board for the best digital waveshape as viewed on the RF Test Set’s oscilloscope display. Dial 311 and then after the 3 cueing beeps, continuously whistle or speak very loudly into the telephone mouthpiece until the RQT beeps again (after about 8 seconds). Dial 411 to activate the RQT transmitter and playback what you just recorded. Adjust R219 on the RQT Control Board for +/- 5 KHz composite DQC and voice deviation. Important: For F.C.C. station licenses that require 11K0F3E modulation or systems using +/- 2.5 KHz peak transmitter deviation, remove jumper PJ102. Dial 411 and verify that the peak deviation is within this limit. Radio tune-up is complete. Enter customer specific information as described in the Owner’s Manual. < end > F.C.C.

FCC ID: AIERIT10-450 Page 5 of 28 EXHIBIT TYPE:Radio Frequency Power Output FCC PART:2.985 DATE:December 14, 1998 PROCEDURE: An RQT-450 was aligned for transmitter operation on 464.600 MHz. (Fo) per the tune-up procedure outlined in the preliminary manual. The output of a variable DC power supply was applied to the external DC power terminals of the unit. The RQT-450 antenna connector was connected to the input of the HP Power Meter. This device provides a single 50 Ohm resistively loaded input port for all measurements. The voltages across the resistor in series with the final RF power transistor were measured and Ohm’s Law was used to determine the collector current. The DC power supply voltage applied to the unit was varied from 6 to 15 Volts DC. The measured transmitter output power remained constant across this range of input voltages. This is attributable to the fact that supply voltages to the transmitter are regulated to a fixed voltage regardless of the applied power supply voltage.

The HP Test Set’s Audio Generator output was connected to the Transmitter Board’s TX MOD. The frequency response of the modulator was determined to be flat within +/-1.5 from 10 Hz to 27,000 Hz. The slight variation is response is at a low frequency and is due to the two point synthesizer reference and VCO modulation method. The following pages show the results in tabular and graphical form.
